E! Online has posted an exclusive look at the first teaser promo for 'The Voice' Season 7, which will debut on NBC on Sept. 22. We have our first look at Gwen Stefani and Pharrell, as they join Adam Levine and Blake Shelton in the swivel judges chairs.

The promo features Stefani's famous catchy tune, 'Hollaback Girl,' as we see her and Pharrell join in on Levine and Shelton goofing off.

Stefani replaces Christina Aguilera, who is currently pregnant with her second child. Pharrell is filling in for Cee Lo Green, who announced in February that he would be leaving the show. Aguilera will be returning for Season 8 in the spring of 2015, while Pharrell is expected to fill in for Green permanently. Usher and Shakira, who have filled in for Aguilera and Green for past seasons, told E! Online in May that they will be focusing on music for the time being.

So what do you think, Voice fans? Are you looking forward to the new season?
